Generate and Validate OpenAPI Specifications
Patterns for creating, maintaining, and validating OpenAPI 3.1 specs - code-first, design-first, SDK generation, and doc portals.
Why it matters
Automate the creation, maintenance, and validation of OpenAPI 3.1 specifications for RESTful APIs. This skill supports design-first API development and ensures implementations align with defined contracts.
Outcomes
What it gets done
Generate OpenAPI specifications from code or design.
Validate API implementations against existing OpenAPI specs.
Create API documentation and client SDKs from specifications.
Maintain and update OpenAPI specifications throughout the API lifecycle.

OpenAPI Spec Generation
Covers creating, maintaining, and validating OpenAPI 3.1 specs via code-first or design-first approaches, plus client SDK generation and documentation portal setup. Use when creating, generating, or validating an OpenAPI spec for a RESTful API.
What it does
Patterns for creating, maintaining, and validating OpenAPI 3.1 specifications for RESTful APIs. Covers writing API documentation from scratch, generating a spec from existing code (code-first), designing the API contract before implementation (design-first), validating a running implementation against its spec, generating client SDKs from a spec, and setting up an API documentation portal.
When to use - and when NOT to
Use when creating API documentation from scratch, generating OpenAPI specs from existing code, designing API contracts with a design-first approach, validating an API implementation against its spec, generating client SDKs from a spec, or setting up an API documentation portal. Not for tasks unrelated to OpenAPI spec generation - it explicitly stays out of scope for other API or documentation domains.
Inputs and outputs
Input is either existing API code for code-first generation, or the intended API contract for design-first authoring, plus the target OpenAPI version (3.1). Output is a validated OpenAPI specification document, and, where requested, generated client SDKs or a published documentation portal. For detailed patterns and examples, it points to resources/implementation-playbook.md.
Integrations
References its own companion resource, resources/implementation-playbook.md, for detailed patterns and worked examples beyond this overview.
Who it's for
API developers and platform teams who need a validated, complete OpenAPI 3.1 spec, whether generated from code or authored design-first, rather than an incomplete or drifted API contract.
